System Description

1. In addition to conventional mechanical key and wireless door lock control functions, the smart access system with push-button start enables door locking/unlocking, steering lock releasing, engine starting and luggage compartment door opening without operating the key. The only requirement is that the key is in the user's possession.
   • This system is controlled by the certification ECU. When the certification ECU detects the presence of the key in one of the detection areas, it identifies and checks the ID code, and outputs operation signals to the related ECU in accordance with their functions.
   • The detection areas are formed by 7 oscillators and 1 antenna (4 door oscillators, 1 luggage compartment antenna, 1 luggage compartment oscillator, and 2 indoor oscillators).

1. Precautions for the entire system:
   • Be sure to carry the key during inspection of the smart access system with push-button start.
   • As weak radio waves are used to detect the key, the key detection area may decrease, or the key may not be detected correctly in the following situations:
     1. The key battery is depleted.
     2. Any facilities that generate strong radio waves, such as a TV tower, power plant, portable media players, broadcast station or gas station, are located near the inspection site.
     3. A wireless device, such as a cellular phone, is carried with the key.
     4. The key is in contact with or covered with metal.
     5. Another wireless door lock control function is operated near the vehicle.
     6. The key is located near a device that generates high voltage or noise.
   • The key may be difficult to operate for a reason relating to the vehicle body shape.
   • The key may not be detected correctly if it is around the vehicle's windows, the door handle or center of the bumper, even when it is in the detection area outside the vehicle.
   • The key may not be detected correctly if it is on the instrument panel, rear package tray or floor, or in the glove box, even when it is in the detection area inside the vehicle.
   • The engine cannot be started even when the key is in the detection area inside the luggage compartment.
   • The key may not operate if the key is not held properly.
   • The smart access system with push-button start does not operate in the following conditions:
     1. The smart access system with push-button start is canceled.
     2. The key battery is completely depleted (the indicator does not blink when pushing any of the buttons on the key).

1. Key:

   The key consists of a mechanical key, a transmitter function for the wireless door lock control and a transceiver for the smart access system with pushbutton start.

   • The transceiver function for the smart access system with push-button start receives the signals from the oscillators and sends the ID code to the door control receiver.
   • The transmitter function for the wireless door lock control has a LOCK switch, UNLOCK switch, LUGGAGE COMPARTMENT switch and PANIC switch.
   • This mechanical key works for the driver door, luggage compartment door and glove box, but cannot start the engine.

   A total of 7 keys can be registered.

2. Oscillator (each door oscillator, front and rear indoor oscillator, luggage compartment oscillator, luggage compartment antenna)

   Each oscillator transmits the request signal received from the certification ECU, and forms a key detection area to detect the presence of a key. The detection area formed by each door oscillator and luggage compartment outer antenna is approximately 0.7 to 1.0 m (2.3 to 3.3 ft.) from the outside handle of each door or the center of the rear bumper.

   • The detection area of each door oscillator is formed by transmitting a request signal every 0.25 seconds while the engine switch is off and each door is locked. In this way, it detects the proximity of a key. During entry lock, the detection area is formed with the lock switch ON.
   • The detection area of the luggage compartment antenna is formed when the luggage door opener switch is ON.
   • The detection area of the indoor oscillator (for front and rear) is formed when the driver door is opened or closed, during start ignition, when a warning is activated, or when the lock switch is ON.
   • The detection area of the luggage compartment oscillator is formed when the luggage compartment door is closed or the luggage compartment door opener switch is pressed.

1. The smart access system with push-button start has the following functions.
   ENTRY FUNCTION OPERATION
   
   

   Function	Outline
   Mechanical Key	Operation is same as conventional mechanical key.
   Wireless Door Lock Control	This function remotely locks and unlocks all doors or luggage compartment. Operation is same as wireless door lock control system. However, the receiver in certification ECU uses entry door control receiver to control locking and unlocking.
   Entry Illumination	When person carrying key enters detection area, door will enter unlock standby mode and map light and door mirror foot light will illuminate.
   Entry Unlock	When key is located in detection area of door oscillator, door will unlock by touching inside of outside door handle.
   Entry Unlock Mode Switching (see CUSTOMIZE PARAMETERS  )	Changes doors that can be unlocked with entry unlock function between 4 modes. Driver door unlock mode Doors on one side unlock mode One door unlock mode All door unlock mode
   Entry Lock	When key is located in detection area of door oscillator and engine switch is off, door can be locked by pressing lock switch on outside door handle.
   Entry Luggage Compartment Open	When key is in detection area of luggage compartment antenna, luggage compartment door opens by pressing luggage compartment door opener switch.
   Memory Call	This function operates driving position memory system in accordance with key ID code.
   Entry Power Window Function	Pressing door handle entry lock switch for approx. 3 seconds or more causes all power windows and sliding roof to close while sounding wireless buzzer.
   Key Lock-in Prevention	Prevents lock-in of key if door is locked using outside door handle while key is still inside vehicle. If all doors locked and luggage compartment door is closed while key is still in luggage compartment, warning buzzer sounds. If luggage compartment door opener switch is operated, luggage compartment door can be opened.
   Warning	When any of situations below occur, smart access system with pushbutton start causes certification ECU to sound buzzer in combination meter and wireless door lock buzzer, and display information in order to alert driver. Shift lever not on P (power source cut reminder) vehicle exit warning Key reminder warning Shift lever on P (power source cut reminder) vehicle exit warning Entry door ajar warning Passenger has brought key out of vehicle warning Key is not within detection area warning Key lock-in prevention function buzzer (for cabin) Key lock-in prevention function buzzer (for luggage compartment) Key battery low warning
   Battery Saving	If key is constantly located within actuation area of door oscillator, system maintains periodic communication with key. Therefore, if vehicle remains parked in that state for long time, key battery and vehicle battery could be drained. For this reason, vehicle has controls for saving battery power.
   Key Cancel (see CUSTOMIZE PARAMETERS  )	Following key functions can be canceled. Entry Unlock/Lock Entry Ignition Memory Call Entry Luggage Compartment Open Key Lock-in Prevention Warning

Push the LOCK/UNLOCK/PANIC/LUGGAGE COMPARTMENT switch on the key to operate each function.

1. The detection area is formed by communication between a door oscillator and the certification ECU when the door is locked in order to detect the person carrying the key.
2. When the person carrying the key enters the detection area around the vehicle, the matching of the ID codes for a door oscillator and key will automatically be performed. After the matching is completed, the door will enter unlock standby mode.
3. In unlock standby mode, the antenna built into the outside handle starts sensing. If the outside handle is held (the back side of the handle is touched), the door unlock operation will be performed. At this time, the hazard warning light blinks twice and the wireless door lock buzzer sounds twice.
4. If any of the doors are not opened after a door unlock operation, all doors will automatically lock after 60 seconds.

1. After leaving the vehicle carrying the key, push the lock switch on the outside handle when all the doors are closed.
2. The certification ECU determines whether the key is located inside or outside of the cabin based on the information from a door oscillator and indoor oscillator. Then matching of the ID codes is performed.
3. When the matching result shows that the ID codes of the key and indoor oscillator do not match and the ID codes of the key and door oscillator match, the door lock function will operate. At this time, the hazard warning lights blink once and the wireless door lock buzzer sounds once.
4. If the key is located inside of the cabin, the door lock function will not operate and the alarm buzzer (beep sound) will sound for 2 seconds.

Stand in front of the luggage compartment with the key and push the luggage door opener switch to start the matching of the ID codes for the luggage compartment antenna. If the ID codes match, luggage compartment door open operation will be performed.

1. If you attempt to lock the door through keyless operation (move the lock knob to the lock position and then close the door) with the key in the cabin, the system determines that the key is located in the cabin and unlocks the door.
2. If the luggage compartment is closed with the key in it, the alarm will sound and the luggage compartment can be opened only when all the doors are locked in order to prevent key lock-in in the vehicle.

In order to improve ease of entering and exiting the vehicle at night, the map light and door mirror foot area light illuminate when the key is brought near the vehicle.

• Control Information:

  Holding the key and bringing it within the vehicle exterior detection area causes the door to enter unlock standby. At this time, the map light and door mirror foot light illuminate.

• Precaution:

  The entry illumination function operates when the key is outside the vehicle exterior detection area for 3 seconds or more, and is then brought within the vehicle exterior detection area. If the key is not first brought outside the vehicle exterior detection area, the entry illumination function will not operate.

1. After locking all the doors through the wireless lock operation or entry lock operation, pressing the door handle lock switch for 3 seconds or more operates the door window close operation of all of the windows and the sliding roof close operation.
2. If the entry power window function is operating and the door handle lock switch is released, the entry power window operation will stop.
3. The wireless buzzer sounds while the entry power window function is operating.

   HINT:

   For more information about the entry power window function, refer to the power window control system.

After unlocking the driver door using the key ID and opening the driver door, the seat automatically moves to the position associated with the key ID.
